Main Features of Hardbanding:

BoTn is famous for a complete series of high performance anti-wear & friction-reduction hardbanding wires, BoTn1000, Botn3000 and Botn5000. The tests results prove that the materials have perfect performance of anti-wear and friction-reduction under downhole conditions.

BoTn1000: Sufficient hardness (HRC58-62) and good anti-wear property which can triple drill tool joint life. It can be spplied to surfacing welding for new & used tool joint, heavy weight drill pipe and various downhole instruments surface.

BoTn3000: sufficient hardness (HRC58-62) and good anti-wear property which can protect drill pipe to the maximum extent. Perfect friction-reduction properly that can reduce the torque of the drilling string.

BoTn5000: excellent friction-reduction property, which can reduce the casing wear. Tight combination between Botn5000 hardbanding and base metal of tool joint, no spalling, no chipping.

Main Features of Internal Coating:

TC-2000 is epoxy-phenolic material, which can be used in a wide range of temperatures and PH conditions.

TC-2000SS is epoxy-phenolic coating, for use in high temperature and pressure environment of natural gas wells with high content of H 2S and CO 2.

TC2000P is an epoxy-novolac powder coating, which can be used in gas production environments containing H 2S and CO2 with higher temperature(400 ℉)and higher pressure conditions.

Other Types of Drill Pipe We Can Do:

KINGWELL Sour Service Drill Pipe

KINGWELL Sour Service Drill Pipe is a type of propriety product with capability of resist to hydrogen sulfide stress corrosion to facilitate the drilling activities in H2S environment.

Size range: Kingwell sour service drill pipe is available for drill pipe ranging in size from 2 3/8 to 6 5/8 inches.

KINGWELL Aluminum Alloy Drill Pipe

KINGWELL Aluminum Alloy Drill Pipe features low specific weight, high flexibility, good corrosion resistance, thus more suitable for extra deep well, horizontal well, high corrosive medium well, directional well and other wells with complicated conditions.

KINGWELL Efficient Cuttings Bed Clean Drill Tool

KINGWELL Efficient Cuttings Bed Clean Drill Tool is proprietary product which designed specifically to improve hole-cleaning performance in horizontal or complex non-conventional wells.

KINGWELL Double-walled Drill Pipe

KINGWELL Double-walled Drill Pipe is composed of two layers drill pipe. It is mainly used in reverse circulation drilling technique. The outside drill pipe is the transmission medium of torque and pressure, the space between outside drill pipe and inside drill pipe is a channel for pumping for circulating medium to well bottom, the inside drill pipe return the circulating medium and rock chips to the outside.

Size Range (OD of external layer pipe): normally 5”, 5 1/2”, 5 7/8”, 6 5/8”, 7 5/8”,8 1/2”, 9 1/2” and 10”.

KINGWELL Non-slip-cut(NSC) Drill Pipe

KINGWELL Non-slip-cut(NSC) Drill Pipe is specially designed for solving problems like the damage to the drill pipe body by the slip cut, the low operation efficiency of double-elevator, and the high labor intensity in the operation of TIH and TOH. This product adds one more shoulder positioned close to the box end than normal API standard drill pipe.

Size range: 4”, 4 1/2”, 5”, 5 1/2”, 5 7/8”, and 6 5/8”
